Sumitomo Chemical SUMIKASUPER LCP E6006L (30% glass fibre; high strength, low shrinkage); SUMIKASUPER LCP Technical Note, Version 04 / Nov. 2023, typical values.
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Plastic ABS is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic ABS stronger than Plastic LCP GF30?
Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 38.1 MPa for Plastic ABS (3.02x).
Which is lighter, Plastic ABS or Plastic LCP GF30?
Plastic ABS is lighter: 1,100 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.
Which is stiffer, Plastic ABS or Plastic LCP GF30?
Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 1.96 GPa for Plastic ABS, so the same part in Plastic LCP GF30 deflects less under the same load.
Which is lighter for the same job, Plastic ABS or Plastic LCP GF30?
For the same stiffness or strength: Plastic LCP GF30 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be
Plastic ABS
Plastic LCP GF30
Stiff rod or tie (tension)
4x heavier
lighter
Stiff beam (bending)
1.65x heavier
lighter
Stiff panel or plate
23% heavier
lighter
Strong rod or tie
2.06x heavier

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Which conducts heat better, Plastic ABS or Plastic LCP GF30?
Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.17 W/m·K for Plastic ABS.
Which expands less with temperature?
Plastic LCP GF30 expands less: 20 µm/m·K against 95 µm/m·K for Plastic ABS.
